AC POWER SUPPLY/BATTERY POWER
The meter may be powered the following ways:
Batteries only
Typical operating time when using the three (3) each
AA alkaline batteries only:
Up to 1 year in display mode only, no data logging,
no alarms.
Up to 1 month with data logging on at a 1 minute
recording rate, with no alarms. Higher capacity
memory cards require more power to operate;
therefore, larger cards will exhaust the batteries
more rapidly.
AC power supply only
If the AC power supply is being used without
batteries, in the event of a power outage, the meter
will turn off and data logging will stop.
AC power supply and batteries together
Using the AC power supply and batteries together
allows the batteries to act as a backup power supply
in the event of a power outage.
When using the AC power supply and batteries
together, the batteries will need to be replaced
periodically to insure they have suf cient power to
operate the meter during a power outage (see the
“Battery Replacement” section).

MINIMUM AND MAXIMUM MEMORY
There are six points that are automatically recorded
into memory:
• Minimum Ambient Temperature Achieved
• Maximum Ambient Temperature Achieved
• Minimum Ambient Relative Humidity Achieved
• Maximum Ambient Relative Humidity Achieved
• Minimum Probe Temperature Achieved
• Maximum Probe Temperature Achieved
Minimum and maximum memories are NOT
programmable. The minimum value recorded into
memory is the minimum reading achieved since the
last time the memory was cleared. The maximum
value recorded into memory is the maximum reading
achieved since the last time the memory was
cleared. The minimum and maximum memories are
maintained over the period since the memory was
last cleared.
VIEWING MINIMUM/MAXIMUM MEMORY
Press the MIN/MAX button, the display will show
“MIN” at the bottom left side of the display indicating
that the minimum memory values are being
displayed.
Press the MIN/MAX button a second time, the
display will show “MAX” at the bottom left side of the
display indicating that the maximum memory values
are being displayed.
Press the MIN/MAX button a third time to return to
the current temperature/humidity display (MIN/MAX
will no longer appear on the display).
CLEARING THE MINIMUM/MAXIMUM MEMORIES
Clearing the Minimum/Maximum memories will
set both the minimum and maximum values for all
readings to the current display readings.
The meter does not have to be in the Min/Max
memory display mode to clear the minimum/
maximum memories.
To clear the minimum and maximum memories,
press and hold the MIN/MAX button for 3 seconds,
all of the LCD segments will appear on the display for
approximately 3 seconds indicating that the minimum
and maximum memories have been cleared.
The minimum and maximum memories are also
cleared when the meter is turned off.
EXAMPLE - USING THE MEMORY TO MONITOR A
REFRIGERATOR/FREEZER
Following is a simple example of how to use the
Min/Max memory to monitor the temperature inside
a refrigerator or freezer. This example is provided
only as a helpful guide and is not intended to replace
existing facility requirements or procedures.
With the meter installed and monitoring the desired
location, keep a notebook or spreadsheet as a
manual log.
1. At the same time every day, record the following
into the manual log:
• Current Date and Time
• Current Readings
• Minimum Readings
• Maximum Readings
2. Once the above items have been manually
recorded, clear the memory.
By clearing the memory each day, the minimum
and maximum memory will provide a record of the
minimum and maximum readings that have been
achieved over the past 24 hour monitoring period.
The memory allows the user to see if any readings
went outside of an acceptable range.
For monitoring overnight or on weekends:
1. Prior to leaving for the night or weekend, record
the following into the manual log:
• Current Date and Time
• Current Readings
• Minimum Readings
• Maximum Readings
2. Once the above items have been manually
recorded, clear the memory.
3. First thing upon returning from overnight or the
weekend, record the following into the manual
log:
• Current Date and Time
• Current Readings
• Minimum Readings
• Maximum Readings
By following the above procedure, the minimum
and maximum memory will provide a record of the
minimum and maximum readings that have been
achieved over that time period. The memory allows
the user to see if any readings went outside of an
acceptable range.
ALARMS
Independent High/Low alarms may be set for all
readings (ambient temperature, relative humidity and
probe temperature). Temperature alarm limits may
be set in 0.1° increments. Relative humidity alarm
limits may be set in 0.1% RH increments.
Each High/Low alarm limit may be independently

monitoring.
ALARM SOUNDING
With an alarm enabled, when a reading being
measured is outside the alarm limit that has been
set (equal to or lower than the low alarm set point, or
equal to or greater than the high alarm set point):
  will  ash on the display next to the
measurement that is alarming (ambient
temperature, ambient relative humidity or probe
temperature).  will continue to  ash next to the
measurement until the measured value returns to
an in-range condition.
The red LED will  ash continuously for the  rst 10
seconds, and will then  ash every 10 seconds
until the measured value returns to an in-range
condition.
The audible alarm will sound continuously for the
 rst 10 seconds, and will then sound every 10
seconds until the measured value returns to an
in-range condition.
While alarming, the sound may be turned off by
pressing the SET button (“Off” will appear on the
display), it is not recommended to turn off the
alarm sound. This will turn off the alarm sound
and no audible alarms will sound while the alarm
sound is turned off. The alarm sound may only be
turned back on by reaching and alarm condition and
pressing the SET button to turn the sound back on;
therefore, it is not recommended to turn off the
alarm sound. The  ashing  and red LED alarm
are not affected by this setting.
